ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch] This patch introduces common.[ch] which are used only in the arch/arm/mach-exynos/ directory. The common.c file merges the cpu.c, init.c, irq-combiner.c and irq-eint.c files which are used commonly on EXYNOS SoCs and the common.h file replaces with plat/exynos4.h file.

ARM: EXYNOS: allow dt based discovery of mct controller using clocksource_of_init Add entries to __clksrc_of_table so that Exynos MCT controller is discoverable using call to clocksource_of_init. With this change, it would be appropriate to rename the function 'exynos4_timer_init' as 'mct_init' since it aptly describes this function. Additionally, the 'init_time' callback of all machine descriptors for exynos platforms that were previously set to 'exynos4_timer_init' are now set to either 'mct_init' or 'clocksource_of_init'.

ARM: exynos: move exynos4210-combiner to drivers/irqchip Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init for GIC init). This commit split the irqchip initialization into 2 calls to of_irq_init. This does not work because of_irq_init requires interrupt parents to be in the match list. Rather than reverting exynos changes, make it do the proper thing by using IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.
